108 | help | |
109 | Tmpfs is a file system which keeps all files in virtual memory. | |
110 | ||
111 | Everything in tmpfs is temporary in the sense that no files will be | |
112 | created on your hard drive. The files live in memory and swap | |
113 | space. If you unmount a tmpfs instance, everything stored therein is | |
114 | lost. | |

116 | See <file:Documentation/filesystems/tmpfs.txt> for details. | |

123 | help | |
124 | POSIX Access Control Lists (ACLs) support additional access rights | |
125 | for users and groups beyond the standard owner/group/world scheme, | |
126 | and this option selects support for ACLs specifically for tmpfs | |
127 | filesystems. | |
128 | ||
129 | If you've selected TMPFS, it's possible that you'll also need | |
130 | this option as there are a number of Linux distros that require | |
131 | POSIX ACL support under /dev for certain features to work properly. | |
132 | For example, some distros need this feature for ALSA-related /dev | |
133 | files for sound to work properly. In short, if you're not sure, | |
134 | say Y. | |
135 | ||
136 | To learn more about Access Control Lists, visit the POSIX ACLs for | |
137 | Linux website <http://acl.bestbits.at/>. | |

144 | Extended attributes are name:value pairs associated with inodes by | |
145 | the kernel or by users (see the attr(5) manual page, or visit | |
146 | <http://acl.bestbits.at/> for details). | |
147 | ||
148 | Currently this enables support for the trusted.* and | |
149 | security.* namespaces. | |
