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

157#
158# 01_all_misc-fix.patch.bz2
159# 02_sparc_another-fix.patch.bz2
160#
161# This ensures that there are a set order, and you can have ARCH
162# specific patches.

164# If you however give an argument to epatch(), it will treat it as a
165# single patch that need to be applied if its a file. If on the other
166# hand its a directory, it will set EPATCH_SOURCE to this.

995# archive. one way to determine this is by running the following commands:
996# strings <pdv archive> | grep lseek
997# strace -elseek <pdv archive>
998# basically look for the first lseek command (we do the strings/grep because
999# sometimes the function call is _llseek or something) and steal the 2nd
1000# parameter. here is an example:
1001# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1002# lseek
1003# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1004# lseek(3, -4, SEEK_END) = 2981250
