I'm using ramdisk, and get some error when booting, the udhcpc can't
write resolv.conf (No space left on device) and the rpm-postinsts fail.
my analysis:
for the former, I only find some info in ./default/volatiles/00_core,
the /etc/resolv.conf is a link to /var/run/resolv.conf, but I have no
idea about udhcpd's error.
for the latter, rpm-postinsts, the reason is: in rpm-postinsts, all sh
files have been executed, and moved to *.done,
(through /etc/rcS.d/S98configure), but /etc/rcS.d/S98configure have not
been deleted, so it is executed again when booting, but there is no any
*.sh file, so fail. ( as expected, if the /etc/rpm-postinsts/*.sh is
moved to *.sh.done, the /etc/rcS.d/S98configure should be deleted, but
it does exist in the rootfs)
the content of /etc/rcS.d/S98configure is:
for i in /etc/rpm-postinsts/*.sh; do
echo "Running postinst $i..."
if [ -f $i ] && sh $i; then
# rm $i
mv $i $i.done
else
echo "ERROR: postinst $i failed."
fi
done
rm -f /etc/rcS.d/S98configure
I think the for sentence is not so robust as expected when no any *.sh
files.
1. the bootargs in uboot is
root=/dev/ram rw ramdisk_size=65535 console=ttyS1,115200
2. the image type is
ext2.gz.u-boot
3. the `df` after login:
root@xx~#df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 16275 11121 4335 72% /
devtmpfs 127664 112 127552 0% /dev
none 127664 112 127552 0% /dev
tmpfs 127664 20 127644 0% /var/volatile
tmpfs 127664 0 127664 0% /media/ram
the rootfs size is 16M, and the ext2.gz.u-boot is 4.1M.
4. indeed, I have encountered one similar problem when using LTIB, that
is:
after login, I can't find the /dev/mtdX, I don't know detail of the
udev, so I checked the auto mount devfs in kernel config, and so get the
expected.
5. the bootlog is:
