Hi.
Sorry for taking so long to reply.
I haven't looked at your patch in a while. I'm just trying to do some catch up
work right now.
I did some experimenting with the package system. The previous idea of running
'make install' into / as a normal user doesn't work very well. 'make install'
likes to change ownership and permissions on directories via the 'install -d'
command. The Trip hint doesn't work well when /usr and other directories are
on other partitions. What seems to be working best is the fakeroot hint...
installing to a fake root as a normal user, and using root to copy the files
over to /. This allows for packages to be made if desired, programs to be
stripped before installing, group write permissions can be fixed, and using cp
-i prevents overwriting existing files.
This is what I have:
# Kernel headers:
# As user 'pkg':
make mrproper
make headers_check
make INSTALL_HDR_PATH=dest headers_install
find dest/include \( -name .install -o -name ..install.cmd \) -delete
mkdir -pv /tmp/linux-2.6.32.25-headers/DESTDIR/usr/include
cp -rv dest/include/* /tmp/linux-2.6.32.25-headers/DESTDIR/usr/include
# As 'root':
cd /tmp/linux-2.6.32.25-headers/DESTDIR
# Install directories that do not already exist:
for dir in $(find . -type d);
do if test ! -d /$dir;
then install -v -d -o bin -g sys /$dir;
fi;
done
# Change ownership to bin:sys, and drop write permission:
find . -type f -exec chown bin:sys {} \; -exec chmod -w {} \;
# Copy files to /, preserving the bin:sys ownership, and prompting before
# overwriting an existing file:
for file in $(find . -type f);
do cp -vi --preserve=ownership $file /$file;
done
# Create a file list, removing the leading '.', and compress it:
find | sed 's...@^.@@' | bzcat -z > \
/var/db/packages/linux-2.6.32.25-headers.txt.bz2
chown bin:sys /var/db/packages/linux-2.6.32.25-headers.txt.bz2
chmod -w /var/db/packages/linux-2.6.32.25-headers.txt.bz2
# Man pages:
# As user 'pkg':
make DESTDIR=/tmp/man-pages-3.25/DESTDIR install
# As 'root':
cd /tmp/man-pages-3.25/DESTDIR
for dir in $(find . -type d);
do if test ! -d /$dir;
then install -v -d -o bin -g sys /$dir;
fi;
done
find . -type f -exec chown bin:sys {} \; -exec chmod -w {} \;
for file in $(find . -type f);
do cp -vi --preserve=ownership $file /$file;
done
find | sed 's...@^.@@' | bzcat -z > \
/var/db/packages/man-pages-3.25.txt.bz2
chown bin:sys /var/db/packages/man-pages-3.25.txt.bz2
chmod -w /var/db/packages/man-pages-3.25.txt.bz2
Tar can't be used to copy the files to / because tar does not have an option to
prompt before overwriting an existing file (like cp -i). The 'install' command
doesn't have an option like this either. If binary packages are made, then tar
can be used because conflicting file names would have been identified already.
This can be cleaned up a bit more, but it seems to work fine. If 'cp -i' finds
a
conflicting file, bzgrep in /var/db/ can find which other package shares the
file.
Su-ing up and and down is a bit messy, so I think using a PKGTMP=/tmp/DESTDIR
set in user 'root' and user 'pkg' environment, and 'cd $PKGTMP/man-
pages-3.25', would be a little easier to work with.
Something else I thought of is identifying hard links in the fake root
directory, and recreating them as relative soft links so they're easier to
copy or tar. Otherwise the hard links become duplicate files.
After adding the gcc patches to chapter 6 I plan to start adding the changes
for this package system, modify the 'creating directories' page to change
ownerships, and get rid of root owning files where possible.
