The initial installation works well.
But if a flash drive is to contain a massive amount of software then it
is reasonable to expect that the user will want to use the stick to
install extra software, herein lies the problem. The stick has to be
mounted by hand.
I have developed a scheme that modifies the installed system at the end
of the installation process so that it will automatically mount the
installation stick as an optical disc when it is inserted.
There are people in the Aussie outback that use the 60 MB stick.
As with all my solutions a stiff G&T is recommended before examining
this one.
The modifications to debian-cd CONF.sh
add
–modification-date=2732101000000000"
to
export i386_MKISOFS_OPTS="-as mkisofs -r -checksum_algorithm_iso \
md5,sha1”
add
–modification-date=2764101000000000"
to
export amd64_MKISOFS_OPTS="-as mkisofs -r \
-checksum_algorithm_iso md5,sha1”
The modification date of the usb stick is read as the UUID of the
stick.
2732 (the supposed year) indicates a 32bit architecture. 2764
indicates a 64 bit architecture.
The final 00 indicates x86_xx.
The line
UUID=2764-10-10-00-00-00-00 \ media/cdrom0 auto
defaults,auto,user,ro,nofail 0 0
is added to fstab
The file99-mount.rules is copied to /etc/udev/rules.d
this file consists of the line
SUBSYSTEM=="block", RUN+="/bin/mount UUID=2764-10-10-00-00-00-00"
The finish-install udeb has been high-jacked and has been modified to
implement these additions. This example uses 64 bit. 2732 would be
used for 32 bit.
I can send a copy of
'finish-install_3.3stick-64_all' to anyone who is interested.
Phil.
