147# Above EPATCH_* variables can be used to control various defaults,
148# bug they should be left as is to ensure an ebuild can rely on
149# them for.

153# Bulk Patches should preferibly have the form of:
154#

157# For example:
158#
159# 01_all_misc-fix.patch.bz2
160# 02_sparc_another-fix.patch.bz2
161#
162# This ensures that there are a set order, and you can have ARCH
163# specific patches.
164#
165# If you however give an argument to epatch(), it will treat it as a
166# single patch that need to be applied if its a file. If on the other
167# hand its a directory, it will set EPATCH_SOURCE to this.

982# strings <pdv archive> | grep lseek
983# strace -elseek <pdv archive>
984# basically look for the first lseek command (we do the strings/grep because
985# sometimes the function call is _llseek or something) and steal the 2nd
986# parameter. here is an example:
987# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
988# lseek
989# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
