Re: [Libguestfs] [PATCH] daemon/RHEL: Choose correct udev settle script.

Subject: [PATCH] daemon/RHEL: Choose correct udev settle script. On RHEL/CentOS 5.4, udevadm settle command does not work. This didn't affect us before, but now that we're using parted for partitioning, we *do* need to wait for udev to settle (because parted isn't waiting for this, unlike sfdisk). This commit chooses the correct program to run. --- daemon/guestfsd.c | 22 +++++++++++++++++++++- 1 files changed, 21 insertions(+), 1 deletions(-) diff --git a/daemon/guestfsd.c b/daemon/guestfsd.c index db0bff9..9375ede 100644 --- a/daemon/guestfsd.c +++ b/daemon/guestfsd.c @@ -976,5 +976,25 @@ device_name_translation (char *device, const char *func) void udev_settle (void) { - command (NULL, NULL, "/sbin/udevadm", "settle", NULL); + static int which_prog = 0; + + if (which_prog == 0) { + if (access ("/sbin/udevsettle", X_OK) == 0) + which_prog = 2; + else if (access ("/sbin/udevadm", X_OK) == 0) + which_prog = 1; + else + which_prog = 3; + } + switch (which_prog) { + case 1: + command (NULL, NULL, "/sbin/udevadm", "settle", NULL); + break; + case 2: + command (NULL, NULL, "/sbin/udevsettle", NULL); + break; + default: + ; + }
