UFS ** Last Mounted on /mnt

[hruodr]

Doing fsck on USB flash memory, I get:

** Last Mounted on /mnt

Where is this information stored? On the flash memory?

fs superblock most likely

It is located in a super block.

grep Last\ Mounted /usr/src/sbin/fsck_ffs/main.c
printf("** Last Mounted on %s\n", sblock.fs_fsmnt);

grep name\ mounted /usr/src/sys/ufs/ffs/fs.h
uint8_t fs_fsmnt[MAXMNTLEN]; /* name mounted on */

No way to avoid writing in the medium? To make a read only ffs?

if you mount it ro it won't write anything on it
after all it works on readonly media
