I have 3 partitions. /dev/hda3 for '/' , /dev/hda1 for /boot and /dev/hda2 for swap.
I boot & then i do a CTRL+ALT+SYSRQ+U. '/' and '/boot' are now remounted ReadOnly.
1) cd '/boot' 2) umount /boot ----> This gives me an error "Device Busy" 3) cd / 4) umount / -------> No error 5) echo $? -----> outputs '0' indicating success. !!!!!!!!
When i do the above by skipping the Sysrq part, i get the usual expected errors.
So is the above behaviour expected ? I tried this on 2.4.19 & 2.5.51. Same results.
I am subscribed to the list
TIA Bourne
