/dev/sda1 is a ordinary partition containing only /boot
why does the kernel report it is in use?
The kernel reports it as being mount
but why
since it normally is as part of the boot process.
looks like you missed thed "for unmounted filesystems" in the subject
/dev/sda1 is mount as /boot
You can usually umount it if no one is in it , or actually using it
umount /boot
df will show the mounted partitions.
umount /boot
fsck /dev/sda1
i know that all *but* i did "umount /boot" and hence i expect to be able
doing a fsck instead once again "touch /forcefsck" and reboot
otherwise the message would not be "/dev/sda1 is in use"
if it is mounted it's "/dev/sda1 is mounted"
so it is in use by whom and why after unmount?
if that would be true it could not be unmounted
