| 3 | The FHS indicates that /etc must be capable of being mounted R/O. |
| 4 | |
| 5 | The FHS also indicates that lock files belong in /var/lock, and /var must |
| 6 | be R/W as soon as possible during boot. |
| 7 | |
| 8 | This patch moves the mtab lock file from the potentially R/O /etc, to the |
| 9 | R/W /var/lock area. This lock file is used when mounting disks and making |
| 10 | other mount adjustments. The _PATH_MOUNTED_TMP is not adjusted, as failing |
| 11 | to write to this file does not cause any functional limitations. |
| 12 | |
| 13 | (Note, if /etc is R/O, then /etc/mtab should be a symlink to /proc/mounts) |
