From f0835514f598eb471edd0d92dc29536afbbcb039 Mon Sep 17 00:00:00 2001 From: Sergei Trofimovich Date: Tue, 23 Jul 2019 08:12:09 +0100 Subject: sys-libs/glibc: expose a knob to downgrade glibc It's not something to be used lightly. Useful when the damage was not yet done to the rest of the system. Usage example: # I_ALLOW_TO_BREAK_MY_SYSTEM=yes emerge -v1 "=glibc-${old-version}" Be prepared to deal with downgrade consequences like disappeared symbols and versions of symbols Package-Manager: Portage-2.3.69, Repoman-2.3.16 Signed-off-by: Sergei Trofimovich --- sys-libs/glibc/glibc-2.29-r2.ebuild | 2 +- sys-libs/glibc/glibc-9999.ebuild | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'sys-libs') diff --git a/sys-libs/glibc/glibc-2.29-r2.ebuild b/sys-libs/glibc/glibc-2.29-r2.ebuild index da78a273d19f..313e5c6b4404 100644 --- a/sys-libs/glibc/glibc-2.29-r2.ebuild +++ b/sys-libs/glibc/glibc-2.29-r2.ebuild @@ -614,7 +614,7 @@ sanity_prechecks() { if has_version ">${CATEGORY}/${P}-r10000" ; then eerror "Sanity check to keep you from breaking your system:" eerror " Downgrading glibc is not supported and a sure way to destruction." - die "Aborting to save your system." + [[ ${I_ALLOW_TO_BREAK_MY_SYSTEM} = yes ]] || die "Aborting to save your system." fi if ! do_run_test '#include \n#include \nint main(){return syscall(1000)!=-1;}\n' ; then diff --git a/sys-libs/glibc/glibc-9999.ebuild b/sys-libs/glibc/glibc-9999.ebuild index 2b0697465d55..0ba2efb974c9 100644 --- a/sys-libs/glibc/glibc-9999.ebuild +++ b/sys-libs/glibc/glibc-9999.ebuild @@ -621,7 +621,7 @@ sanity_prechecks() { if has_version ">${CATEGORY}/${P}-r10000" ; then eerror "Sanity check to keep you from breaking your system:" eerror " Downgrading glibc is not supported and a sure way to destruction." - die "Aborting to save your system." + [[ ${I_ALLOW_TO_BREAK_MY_SYSTEM} = yes ]] || die "Aborting to save your system." fi if ! do_run_test '#include \n#include \nint main(){return syscall(1000)!=-1;}\n' ; then -- cgit v1.2.3-65-gdbad
