Hi,
My TS-7260 using an initramfs, busybox combination that mounts the usb
from /dev/sda1 and then uses swith_root to pivot the rootfs to a the
usb which has a Debian rootfs.
To avoid data loss in the root partition in the event of a power
failure or system crash I want the rootfs to be READ ONLY.
The problem is:
Though I mount the usb as read only and it behaves as a read only
while initramfs is the root file system, when I switch/pivot the file
system it becomes read write.
My initramfs init file is
#!/bin/ash
export PATH="/bin:/sbin:/usr/bin"
echo "AYIM init script running .. "
mount -t proc none /proc
mount -t sysfs none /sys
busybox sleep 15
mount -o ro -t ext2 /dev/sda1 /mnt
busybox umount /proc
busybox umount /sys
exec busybox switch_root /mnt /sbin/init
exec /bin/ash
Furthermore, please give any good suggestions to know whether the usb
device /dev/sda1 is ready to mount. (Now I an just sleeping for 15
seconds)
Thank you
Gajan
