Magically disappeared Sorry, not exactly. The cfdisk action did not cause it of course; it ends with a write command (it is suggested to reboot to make the changes permanent). But until that time it creates a presumably semi-permanent state of /dev/sda10 being in cfdisk and fdisk displays, and at the same time df and mount showing /dev/sda10 mounted as UFS partition on /media mount point. A subsequent reboot cleared that temporary manual /media mount. > ... > What would have happened (as I suggested it previously) if I put that FreeBSD > /dev/sda10 in /etc/fstab ? > That new Linux /dev/sda10 partition would be auto mounted at that mount point, > which would presumably be a source of data for some system or user app ... That test was done by me. # cat /etc/fstab ... /dev/sda10 /media ufs ro,ufstype=ufs2 0 0 ... In this case /dev/sda10 was already a Linux parition per above and the mount failed as shown in boot log: # dmesg ... [ 18.597349] EXT4-fs (sda7): re-mounted. Opts: (null) [ 18.835869] ufs_read_super: bad magic number [ 20.743108] Adding 2933244k swap on /dev/sda5. Priority:-1 extents:1 across:2933244k ... But other bad outcomes are possible (see next post). > ...
