It explains why most people don't see this issue. Why does file-rc cause problems? > Does glibc open the nscd cache files directly rather than communicating > with it via a socket? Or does it communicate via shared memory? Quick look at the source, mmap is used to share database file with mmap MAP_SHARED, so the main communication should be done via a socket. > > rc 827 root mem REG 8,9 217016 228931 /var/db/nscd/passwd > > [Is /var/db even FHS?] FHS states as follows. 5.5.2 /var/lib/misc : Miscellaneous variable data This directory contains variable data not placed in a subdirectory in /var/lib. An attempt should be made to use relatively unique names in this directory to avoid namespace conflicts. Note that this hierarchy should contain files stored in /var/db in current BSD releases. These include locate.database and mountdtab, and the kernel symbol database(s). LDAP or DB data sometimes puts their db files on /var/lib/misc (I think "misc" is vague term, though). Actually debian/patches/fhs-linux-paths.dpatch contains the following changes: --- glibc-2.1.1/sysdeps/unix/sysv/linux/paths.h~ Thu May 27 13:16:33 1999 +++ glibc-2.1.1/sysdeps/unix/sysv/linux/paths.h Thu May 27 13:17:55 1999 @@ -71,7 +71,7 @@ /* Provide trailing slash, since mostly used for building pathnames. */ #define _PATH_DEV "/dev/" #define _PATH_TMP "/tmp/" -#define _PATH_VARDB "/var/db/" +#define _PATH_VARDB "/var/lib/misc/" Another chioce is to use /var/cache - it's for application specific caching data. But currently I use /var/db instead of /var/lib/misc - I have wondered this change is widely accepted. I would like to hear from all you guys about this placement.
