Esta \u00e9 a mel\u00adhor op\u00e7\u00e3o, ape\u00adsar de ser a que demo\u00adra mais tem\u00adpo, mas ficamos com um sis\u00adtema opti\u00admiza\u00addo para o hard\u00adware<\/em> onde ser\u00e1 compilado.<\/p>\n

<\/p>\n

O primeiro pas\u00adso con\u00adsiste em actu\u00adalizar os ficheiros fonte do sis\u00adtema. Numa insta\u00adla\u00e7\u00e3o nor\u00admal do FreeB\u00adSD, estes ficheiros est\u00e3o todos con\u00adti\u00addos no direc\u00adt\u00f3rio \/usr\/src<\/span>. Esta actu\u00adal\u00adiza\u00ad\u00e7\u00e3o \u00e9 nor\u00admal\u00admente efec\u00adtu\u00ada\u00adda com o coman\u00addo cvsup<\/span>. No direc\u00adt\u00f3rio \/usr\/share\/examples\/cvsup<\/span> podem-se encon\u00adtrar exem\u00adp\u00adlos para os v\u00e1rios reposit\u00f3rios CVSup exis\u00adtentes. O ficheiro cor\u00adre\u00adspon\u00addente ao c\u00f3di\u00adgo fonte do sis\u00adtema \u00e9 o sta\u00adble-sup\u00adfile<\/span>. A invo\u00adca\u00e7\u00e3o deste coman\u00addo \u00e9 fei\u00adta como cvsup \u2011L 2 \u2011g sta\u00adble-sup\u00adfile<\/span>.<\/p>\n

Depois do c\u00f3di\u00adgo fonte insta\u00adl\u00ada\u00addo, bas\u00adta exe\u00adcu\u00adtar os seguintes comandos:<\/p>\n

cd \/usr\/src\nmake -j4 buildworld\nmake buildkernel\nmake installkernel\nmergemaster -p\nmake installworld\nmergemaster\nshutdown -r now<\/pre>\n
Caso se dispon\u00adha de um con\u00adfig\u00adu\u00adra\u00e7\u00e3o cus\u00adtomiza\u00adda para o ker\u00adnel<\/em>, especi\u00adfi\u00adca-se essa con\u00adfig\u00adu\u00adra\u00e7\u00e3o com a op\u00e7\u00e3o KERNCONF<\/span>=<configura\u00e7\u00e3o>, nas lin\u00adhas ref\u00ader\u00adentes ao ker\u00adnel<\/em>.<\/p>\n
O coman\u00addo merge\u00admas\u00adter<\/span> serve para inte\u00adgrar as difer\u00aden\u00e7as entre os ficheiros de con\u00adfig\u00adu\u00adra\u00e7\u00e3o insta\u00adl\u00ada\u00addos por defeito e quais\u00adquer mod\u00adi\u00adfi\u00adca\u00e7\u00f5es feitas pelo admin\u00adistrador do sistema.<\/p>\n
Depois dis\u00adto, ficare\u00admos com o sis\u00adtema base actu\u00adal\u00adiza\u00addo.
