Well, it's a tmpfs, so it gets wiped on shutdown anyway. Anything that |
| 26 |
needs the /tmp/jack directory will write to there whether a tmpfs is |
| 27 |
mounted or not, so removing the fstab line wont have any consequences by |
| 28 |
itself. If /tmp/jack gets removed by a boot script, and is actually |
| 29 |
needed, the directory will most likely be recreated by whatever program |
| 30 |
needs it. If not, you can always "mkdir /tmp/jack" long enough to fix |
| 31 |
the program in question. |

I suspect the gentoo script is something simple like "if WIPE_TMP=YES, |
| 38 |
then rm /tmp/*". |

FHS recommends nothing in /tmp survive boot. |

It's bad practice to have a persistent mount point inside of /tmp or |
| 43 |
/var/tmp. |
| 44 |
If your /tmp is a tmpfs of some kind, then the above fstab entry is |
| 45 |
redundant anyway. |
| 46 |
|
| 47 |
The main (possible) problem is some program requires a directory/file to |
| 48 |
exist in /tmp, but doesn't create that directory/file itself. Thats |
| 49 |
just a plain stupid (programming) practice, so I doubt you'll run into |
| 50 |
any issues with removing the fstab entry, and so on. |
