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
148# them for.
149#
150# Patches are applied in current directory.
151#
152# Bulk Patches should preferibly have the form of:
153#
154# ??_${ARCH}_foo.${EPATCH_SUFFIX}
155#
156# For example:
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.
163#
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.

999# strace -elseek <pdv archive>
1000# basically look for the first lseek command (we do the strings/grep because
1001# sometimes the function call is _llseek or something) and steal the 2nd
1002# parameter. here is an example:
1003# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1004# lseek
1005# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1006# lseek(3, -4, SEEK_END) = 2981250
