77 | This option gives you the ability to force a static link of UML. |
78 | Normally, UML is linked as a shared binary. This is inconvenient for | |
79 | use in a chroot jail. So, if you intend to run UML inside a chroot, | |
80 | you probably want to say Y here. | |
81 | Additionally, this option enables using higher memory spaces (up to | |
82 | 2.75G) for UML. | |

103 | While the User-Mode Linux port uses its own root file system for |
104 | booting and normal file access, this module lets the UML user | |
105 | access files stored on the host. It does not require any | |
106 | network connection between the Host and UML. An example use of | |
107 | this might be: | |
1da177e4 | 108 | |
4c9e1385 | 109 | mount none /tmp/fromhost -t hostfs -o /tmp/umlshare |
1da177e4 | 110 | |
4c9e1385 JD |
111 | where /tmp/fromhost is an empty directory inside UML and |
112 | /tmp/umlshare is a directory on the host with files the UML user | |
113 | wishes to access. | |
1da177e4 | 114 | |
4c9e1385 JD |

116 | <http://user-mode-linux.sourceforge.net/hostfs.html>. | |
1da177e4 | 117 | |

118 | If you'd like to be able to work with files stored on the host, |
119 | say Y or M here; otherwise say N. | |

1da177e4 | 124 | help |
4c9e1385 JD |
125 | hppfs (HoneyPot ProcFS) is a filesystem which allows UML /proc |
126 | entries to be overridden, removed, or fabricated from the host. | |
127 | Its purpose is to allow a UML to appear to be a physical machine | |
128 | by removing or changing anything in /proc which gives away the | |
129 | identity of a UML. | |
1da177e4 | 130 | |

139 | help | |
4c9e1385 JD |
140 | The user mode linux management console is a low-level interface to |
141 | the kernel, somewhat like the i386 SysRq interface. Since there is | |
142 | a full-blown operating system running under every user mode linux | |
143 | instance, there is much greater flexibility possible than with the | |
144 | SysRq mechanism. | |
1da177e4 | 145 | |
4c9e1385 JD |
146 | If you answer 'Y' to this option, to use this feature, you need the |
147 | mconsole client (called uml_mconsole) which is present in CVS in | |
148 | 2.4.5-9um and later (path /tools/mconsole), and is also in the | |
149 | distribution RPM package in 2.4.6 and later. | |

156 | help |
157 | If you say Y here, you will have some control over the system even | |
158 | if the system crashes for example during kernel debugging (e.g., you | |
159 | will be able to flush the buffer cache to disk, reboot the system | |
160 | immediately or dump some status information). A key for each of the | |
161 | possible requests is provided. | |
1da177e4 | 162 | |

163 | This is the feature normally accomplished by pressing a key |
164 | while holding SysRq (Alt+PrintScreen). | |
1da177e4 | 165 | |
4c9e1385 JD |
166 | On UML, this is accomplished by sending a "sysrq" command with |
167 | mconsole, followed by the letter for the requested command. | |
1da177e4 | 168 | |
4c9e1385 JD |
169 | The keys are documented in <file:Documentation/sysrq.txt>. Don't say Y |

4c9e1385 JD |
177 | This option enables UML SMP support. |
178 | It is NOT related to having a real SMP box. Not directly, at least. | |
1da177e4 | 179 | |
4c9e1385 JD |
180 | UML implements virtual SMP by allowing as many processes to run |
181 | simultaneously on the host as there are virtual processors configured. | |
1da177e4 | 182 | |
4c9e1385 JD |
183 | Obviously, if the host is a uniprocessor, those processes will |
184 | timeshare, but, inside UML, will appear to be running simultaneously. | |
185 | If the host is a multiprocessor, then UML processes may run | |
186 | simultaneously, depending on the host scheduler. | |
1da177e4 | 187 | |
4c9e1385 JD |
188 | This, however, is supported only in TT mode. So, if you use the SKAS |
189 | patch on your host, switching to TT mode and enabling SMP usually | |
190 | gives you worse performances. | |
191 | Also, since the support for SMP has been under-developed, there could | |
192 | be some bugs being exposed by enabling SMP. | |

206 | This is set to the number of layers of UMLs that this UML will be run |
207 | in. Normally, this is zero, meaning that it will run directly on the | |
208 | host. Setting it to one will build a UML that can run inside a UML | |
209 | that is running on the host. Generally, if you intend this UML to run | |
210 | inside another UML, set CONFIG_NEST_LEVEL to one more than the host | |
211 | UML. | |
