Hi guys,
I encountered this problem during the summer, asked on current@ but
didn't receive response.
When root filesystem is cd9660, the date of the system is set to epoch.
I made some empiric debugging, discovering that the problem strongly
depends on the mountroot setting and not on the different loader used
for cd-boot. Have taken a look at the code and discovered what it seems
to me the responsible of the bug.
kern/vfs_mount.c:1313:
/*
* We mount devfs prior to mounting the / FS, so the first
* entry will typically be devfs.
*/
mp = TAILQ_FIRST(&mountlist);
KASSERT(mp != NULL, ("%s: mountlist is empty", __func__));
/*
* Iterate over all currently mounted file systems and
* the time stamp found to check and/or initialize the RTC.
* Typically devfs has no time stamp and the only other FS
* is the actual / FS.
*/
do {
if (mp->mnt_time != 0)
inittodr(mp->mnt_time);
mp = TAILQ_NEXT(mp, mnt_list);
} while (mp != NULL);
Haven't investigate further, but I think that when the root is cd9660,
mp->mnt_time is 0 and inittodr isn't initialised.
Any idea on how to resolve this?
Bye and thanks in advance,
Dario
