When you restart a daemon the environement of the processus is not clean: for example, with apache (but the same with lighttpd, mysql, rsync...) after a server reboot: # cat /proc/<PID>/environ CONSOLE=/dev/consoleTERM=linuxDEFAULTLEVEL=defaultLC_ALL=fr_FR@euroCRITICAL_SERVICES=checkroot modules checkfs localmount clock bootmiscINIT_VERSION=sysvinit-2.86PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin:/bin:/usr/bin:/sbin:/usr/sbinRUNLEVEL=3PWD=/LANG=fr_FR@euroPREVLEVEL=NBOOTLEVEL=bootSVCNAME=apache2CONSOLETYPE=vtHOME=/SHLVL=2SOFTLEVEL=defaultOLDSOFTLEVEL=boot_=/sbin/start-stop-daemon# after a daemon restart: # cat /proc/<PID>/environ TERM=xtermSHELL=/bin/zshDEFAULTLEVEL=defaultLC_ALL=fr_FR@euroUSER=rootPATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/opt/bin:/usr/i686-pc-linux-gnu/gcc-bin/4.1.2PWD=/rootLANG=fr_FR@euroBOOTLEVEL=bootSVCNAME=apache2CONSOLETYPE=ptySHLVL=1HOME=/rootSOFTLEVEL=default_=/sbin/start-stop-daemon# Reproducible: Always Steps to Reproduce: 1. /etc/init.d/<daemon> restart 2. 3.

this has already been fixed in baselayout-2
I make the test with baselayout-2.0.0_rc6 and the example with mysql after a reboot: cat /proc/<PID>/environ TIMEUNIT=0.1unmanagedparams= CONSOLE=/dev/consoleCHROOT=TERM=linuxSTOPTIMEOUT=1200pidfile=/var/run/mysqld/mysqld.pidNICE=LC_ALL=fr_FR@euroINIT_VERSION=sysvinit-2.86basedir=/usrPATH=/bin:/sbin:/usr/bin!:/usr/sbin+RUNLEVEL=3PWD=/LANG=fr_FR@eurodatadir=/var/lib/mysqlPREVLEVEL=NSVCNAME=mysqlSHLVL=1socket=/var/run/mysqld/mysqld.sockSTARTUPTIMEOUT=50MY_CNF=/etc/mysql/my.cnfMY_SUFFIX=_=/sbin/start-stop-daemonHOME=/rootUSER=root# after daemon restart: cat /proc/<PID>/environ TIMEUNIT=0.1unmanagedparams= CHROOT=TERM=xtermSHELL=/bin/zshSTOPTIMEOUT=1200pidfile=/var/run/mysqld/mysqld.pidNICE=LC_ALL=fr_FR@eurobasedir=/usrPATH=/bin:/sbin:/usr/binQœ:/usr/sbin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.1.2:/opt/blackdown-jdk-1.4.2.03/bin:/opt/blackdown-jdk-1.4.2.03/jre/bin:/opt/binŒPWD=/LANG=fr_FR@eurodatadir=/var/lib/mysqlSVCNAME=mysqlSHLVL=1socket=/var/run/mysqld/mysqld.sockSTARTUPTIMEOUT=50MY_CNF=/etc/mysql/my.cnfMY_SUFFIX=_=/sbin/start-stop-daemonHOME=/rootUSER=root# ...

And trust me it's been cleaned out as the env that restarted it had things like PYTHONPATH in. We have to allow some env vars through - see /lib/rc/conf.d/env_whitelist for all of them. mysql is a bad example as it's init script is horendeous and needs a rewrite. See bug #175783 for a better one. I chose sshd as its init script is simple.
