So here is the whole thing with the LCD pins stored in the EEPROM 8)

#include <EEPROMex.h>
#include <LiquidCrystal.h>

const int memBase    = 0;
uint16_t EEVer         = memBase;     // Version in 16 bit
uint16_t EELcdRS       = memBase + 2; // --> LCD pin RS
uint16_t EELcdEN       = EELcdRS + 1; // --> LCD pin EN
uint16_t EELcdD4       = EELcdEN + 1; // --> LCD pin D4
uint16_t EELcdD5       = EELcdD4 + 1; // --> LCD pin D5
uint16_t EELcdD6       = EELcdD5 + 1; // --> LCD pin D6
uint16_t EELcdD7       = EELcdD6 + 1; // --> LCD pin D7

uint8_t  LcdRS,       // LCD pin RS
         LcdEN,       // LCD pin EN
         LcdD4,       // LCD pin D4
         LcdD5,       // LCD pin D5
         LcdD6,       // LCD pin D6
         LcdD7;       // LCD pin D7
         
LiquidCrystal lcd(0,0,0,0,0,0);

void setup(){
  LcdRS = EEPROM.readByte(EELcdRS);    // LCD pin RS
  LcdEN = EEPROM.readByte(EELcdEN);    // LCD pin EN
  LcdD4 = EEPROM.readByte(EELcdD4);    // LCD pin D4

  LiquidCrystal lcd1(LcdRS, LcdEN, LcdD4, LcdD5, LcdD6, LcdD7);
  lcd = lcd1;  // <-- this is the matchwinner!                

  lcd.begin(16,2);

  lcd.print("hello world");
