Release v3.1
============
Command-line interface changes
------------------------------
+ The initial command is not search in "." anymore, unless the "./"
prefix is specified or unless "." is in $PATH, as expected.
+ The "-B" and "-Q" options are obsoleted by the new "-R" option.
This latter is equivalent to "-B -r", as there was actually no point
at using the "-B" option without "-r".
+ A warning is now emitted when the rootfs is specified à la
chroot(1), that is, without using "-r" or "-R".
The old command-line interface is not documented anymore, but it will
be still supported for a couple of releases. Although, users are
strongly encouraged to switch to the new one:
====================== =================
old CLI new CLI
====================== =================
proot rootfs proot -r rootfs
proot -B rootfs proot -R rootfs
proot -B -r rootfs proot -R rootfs
proot -Q qemu rootfs proot -R rootfs -q qemu
proot -Q qemu -r rootfs proot -R rootfs -q qemu
======================= =======================
Extensions
----------
+ The "kompat" extension ("-k" option) has been greatly enhanced. For
example, it can now make programs from Ubuntu 13.04 32-bit run on
RedHat 5 64-bit:
rh5-64$ proot -k 3.8 -R ubuntu-13.04-32bit/ ...
+ The "fake id0" extension ("-0" option) handles more syscalls:
mknod(2), capset(2), setxattr(2), setresuid(2), setresgid(2),
getresuid(2), and getresgid(2).
Miscellaneous
-------------
+ PRoot is now compiled with large file-system support (LFS), this
make it works with 64-bit file-systems (eg. CIFS) on 32-bit
platforms.
+ The special symbolic link "/proc/self/root" now points to the guest
rootfs, that is, to the path specified by "-r" or "-R". Just like
with chroot(2), this symlink may be broken as the referenced host
path likely does not exist in the guest rootfs. Although, this
symlink is typically used to know if a process is under a chroot-ed
environment.
+ Under QEMU, LD_LIBRARY_PATH is not clobbered anymore when a guest
program is launched by a host program.
+ When seccomp-filter is enabled, this release is about 8% faster than
the previous one.
+ A couple of bugs reported by Scan Coverity are fixed.
