i used http://en.gentoo-wiki.com/wiki/LTSP but this seems to be not working for me.

i continue here: http://flowledge.nl/gentoo/ltsp/, that gives the option to manually build the client.

the thinclient loads ramdisk and kernel, but then the ltsp script cannot remount the rootfs rw. i get something like
Quote:
remounting root fs read/write
Skipping /etc/mtab initialization (ro root?)
you must be root to do this

skip missing mtab
no such file trying open /dev/ROOT

/dev/BOOT

cant create lock file


the corresponding lines in the initscript are:
Code:
        # Should we mount root rw ?  the touch check is to see if the / is
        # already mounted rw in which case there's nothing for us to do
        if mount -vf -o remount / 2> /dev/null | \
           awk '{ if ($6 ~ /rw/) exit 0; else exit 1; }' && \
           ! touch -c / >& /dev/null
        then
                ebegin "Remounting root filesystem read/write"
                mount -n -o remount,rw / &> /dev/null
                if [[ $? -ne 0 ]] ; then
                        eend 2 "Root filesystem could not be mounted read/write :("
                        if [[ ${RC_FORCE_AUTO} != "yes" ]] ; then
                                sulogin ${CONSOLE}
                        fi
                else
                        eend 0
                fi
        fi
        if [[ ${BOOT} == "yes" ]] ; then
                local x=
                local y=

                #
                # Create /etc/mtab
                #

                # Don't create mtab if /etc is readonly
                if ! touch /etc/mtab 2> /dev/null ; then
                        ewarn "Skipping /etc/mtab initialization (ro root?)"
                        return 0
                fi

                # Clear the existing mtab
                > /etc/mtab

                # Add the entry for / to mtab
                mount -f /

                # Don't list root more than once
                awk '$2 != "/" {print}' /proc/mounts >> /etc/mtab

                # Now make sure /etc/mtab have additional info (gid, etc) in there
                for x in $(awk '{ print $2 }' /proc/mounts | sort -u) ; do
                        for y in $(awk '{ print $2 }' /etc/fstab) ; do
                                if [[ ${x} == ${y} ]] ; then
                                        mount -f -o remount $x
                                        continue
                                fi
                        done
                done

                # Remove stale backups
                rm -f /etc/mtab~ /etc/mtab~~
        fi

Too bad, I was just going to look at your problem. My plan was to test and release 5.2.3, and also look at the layman issue you mentioned in the ltsp bug.

oh thank you.
but i had another bugs while trying to get the script run.

would'nt it be useful to have a manual howto without that script. i think its very fragile regarding changes in portage and the whole gentoo system.

i made some changes, and was confident but after 6h the script stopped again while trying to emerge lvm.

i'll post these bugs on bugzilla.
