If disk space is very tight, the --strip-all option can be used on the
binaries in /{,usr/}{bin,sbin} to gain several more megabytes.
Do not use this option on libraries—they will be destroyed.

I think it was only the .a libraries that get damaged w/ --strip-all
(makes it unlinkable since you remove the symbols). Not sure what the
size difference is, but symbols do not take up much space usually.

Regards, Edgar We already spend more time in LFS explaining GRUB than with any other single package in LFS or BLFS with the exception of Xorg (if you count that as a single package). We don't see our role as explaining every little nuance. GRUB2 *is* complex. It supports: Multiple languages Network PXE Serial Ports CDROMs Floppies Partition Formats Operating Systems Disk Hardware BIOS Types My purpose was to explain how to make GRUB work in what I considered to be the most common instance: ext3 on a standard hard drive as /dev/sdax, standard ps2 or usb keyboard, and standard vga monitor. Explaining a comment line in a generated configuration file seems to be overkill. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

Can i build lfs without a dedicated partition ?
Hi , I just started with lfs using book version 6.6 . I had previously started with book ver 6.3 and in dat , author said it is okey to build lfs without a partition , in a directory . But in the new version of the book , no such thing is mentioned . So somebody advice me on this . Do i really need a dedicated partition for the build or can i build it in a directory as said in ver 6.3 ? If a dedicated partition is essential , can i use a usb stick ? -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

The comment about "exec tail" comes from /etc/grub.d/40_custom, in which the command does exist - grub.cfg just copies the comment lines from each config file and doesn't include the actual tail command. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

I write a simple libxxx.so lib and a app link to it. --strip-all the
libxxx.so. And the app works fine.
