Read-only issue when using unionfs-fuse
Hi,
Because aufs is not available in linux-image-2.6.35-trunk-686 in the
experimental branch, I decided to try unionfs-fuse function in the
Debian live. The created Debian Sid live, running with kernel 2.6.32-23,
can boot, however, it shows me a lot of "Read-only" errors.
Here is how to reproduce:
1. Install live-build 2.0~a29-1
2. Run the following command to create the Debian iso
====================================
#!/bin/bash
mirror_url=http://free.nchc.org.tw/debian
mirror_security_url=http://free.nchc.org.tw/debian-security
lb config --mirror-binary $mirror_url --mirror-binary-security
$mirror_security_url
lb config --mirror-bootstrap $mirror_url
lb config --mirror-chroot $mirror_url --mirror-chroot-security
$mirror_security_url
lb config --bootstrap-flavour minimal --packages "unionfs-fuse" --apt
apt --apt-recommends false --binary-indices false --bootstrap
cdebootstrap --tasksel none
lb config --volatile false
lb config --initramfs live-initramfs
lb config --username user --bootappend-live "union=unionfs-fuse"
lb config --distribution sid
lb config --linux-flavours 686
lb config --memtest none
lb build
====================================
3. Boot the created binary-hybrid.iso, and you can see the Read-only
errors, for example:
/etc/init.d/mtab.sh: 178: cannot create /etc/mtab: Read-only file system
...
can't create lock file /etc/mtab~782: Read-only file system (use -n flag
to override)
The complete booting process is attached.
Where am I wrong? Any hints?
Thanks in advance.
Steven.
